Connect Broadband — decrease in my internet speed and no response after so many calls and e-mail

Address: Jalandhar, Punjab

Last year my internet speed was 2.62 mbps on oakla speed test and now it is about 300 kbps. My plan is coperate plan so there is no limit and I have also proof for that as I make 1 video and 1 picture of high speed downloading . They now said you will recieve this speee only. That's very annoying
